I've got big issue with my s2000, it's turbo now. It's been a good 2 months and since yesterday it's running on 3 cylinders. I check the compression and it's good. The injector are ok and I changed the coil pack and the spark plug. The weird thing is when I take the coil pack a bit farther.. it runs well... I don't understant at all. I keep the coil pack 2-3 cm far away from the spark plug and it runs fine... if I plug it in right it's stats running on 3 cylinders..

I need help !!

thx

 

make sure there is nothing in the plug well for the coil pack to arc with, if its arc'ing the plug will get no/very little juice. check the plug boot and the connector inside the boot.

if you have replaced the coil pack and the spark plug (both with new items) then I can't imaging what else it would be. (double check you are using the correct plug and coil pack )

maybe also check the harness going to the coil pack, there might be a loose connection.

 

can it be the computer maybe ? it's a aem ems not perfectly tunned yet. do you think that might me the problem ?

 

doesn't sound like the issue unless something was set wrong.
if you can hold the coil pack a hair back and it runs fine then it doesn't sound like an ems issue. atleast to me.

 

make sure the plugs are tight.... pull out the coil pack (with the spark plug still on), cover it with ur hand and let someone crank the engine... see if ders a leak...


p.s. my old car is boosted now ... do you have any recent pics???
